tal reciprocating movement to the needle bars.

A bracket 34 extends up from the top of the bed plate 3 and has abearing in which is pivotally mounted a rocker arm 35, the lowe1 end otwhich rocker arm is bifurcated and straddles the lam 33. so that as thecam 33 rotates. the upper end of the arm 35 will be rockedlongitudinally.

The stitcletightening device is operated by a cam 24 on the shaft 6which cam gives a reciprocating movement to the shoe 25 .which iseonnnunicated to the rock arm 36 by the rod The'rock arm 36 is rigidlymounted upon a rod 3T secured in standards 4 and 5 parallel to the,shafts and upon the outer end thereof and extends downwardly therefrom.Rigidly mounted upon the rod 3T between the inner sides of the standards4 and 5 are two upwardly-extemling roeli arms 38 and 39, to the upperends of which are pivotally secured the inner ends of a U-shaped pullingrod 40. ImmediatelyY below the opening 41 in the bed plate 3 are twospaced fixed parallel rods 42 and 4I-molmted one above the other in thestandards 4 and 5 between which last rods the pulling rod 4() is adaptedto be. moved. rl`wo grooved pulleys 44 and 45 are loosely mounted upontherod 3T and a similar pulley 46 is secured upon the shaft 6 at theside of the cam 13 around which last pulley is passed a band 4T which inturn passes over pulleys 44 and 45 aml then extends downwardly andpasses around a pulley 4S. 'lhe pulley 4S is mounted upon one end of ashaft 45) mounted in bearings upon the table 1. which shaft has securedthereon a worm 5t), which worm meshes with a worm gear 5; mounted uponone end of a'talte-up roll 53. 'l"he roll 5I is mounted in the frame 54mounted upon said table. and a similar roll 55 is mounted therein at theside of the roll 53. The other ends ol' these rolls are colmecteitbygears 56 and 5T so that they move togetherllxtending upwardly from thetop ot' the bed plate 3 centrally thereol are two standards 5S and :'tlwhich are provided near their lower ends with slots titl and 6l in whichare slidably mounted the needle plates 62 and 63. Suitable mechanism ispro vided for rta-iprocating the needle plates 62. (i3 simultaneouslybut in opposite directions. ln the. construction herein shown the frontneedle plate 62 is provided at one end .with a projecting arm 64`towhich is p'ivotally connected the upper end of the end of a rockinglever 66 that is pivotally mounted centrally upon the stud 67 mounted inthe top of the bed plate 3. vThe rear needle plate 63 has a similarbracket 68 rigidly seemed thereto which is also pro'- vided with a slot168 that' receives a pin 169 secured in the opposite end of said rock Iing lever 66. With this construction it will be seen that when the arm64C, moves to the right, Fig. 12, thereby to move the Afront needleplatei62 to the right, the bracket 65 which is rigid with the needleplate 62 will Vact on the pin 166 thereby to swing Vthe rocking lever 66about its central pivot. This turning movement ofthe lever 66 lWilloperate through the pin 169 and bracket 68 to move. the rear needleplate 63 to the left.

The pin-and-slot connections between the rocking lever 66 and thebrackets 65 and 68 permit of this movement without causing any bindingof the parts. Similarly, when the projection 64 is moved to the left,Fig. 12, the front needle plate 62 will be moved to the left. but therear needle plate will be moved to the right through the connectionsabove. described. These needle plates have provided between them a lon-2" litudinally-extending slot 69 throuOh which passes the completedfabric when tie machine is operated. l On the outer surfaces of theneedle plates are formed a series of slots in the usual manner for-thereception of the needles T0. The needles are of the usual kind used inmachinesvof this class and the hubs 71 project outwardly from the slots.

Each needle-lifting plate is provided with a needle-lifting bar 72 whichare fastened together and slide upon the needle plates. the frontneedlelifting bar being supported upon the upper ends of medle-liftingrods 16 and l1T y\vhereb a vertical reciprocating movement is impartedto the needles. The hubs of the needles rest upon the top of theneedle-lifting bars. and a slotted bar 73 is adapted to rest upon saidbars to hold the lmbs of the needles against displacement. and aretaining strip T4 resti/empoli said slotted bar and the hubs oftheifieedles, upon which retaining strip is mounted the upperi'nwardly-extemling leg of an inverted L- ('ap T5 is secured to Laaaaioathrough an aperture in a oraelr'et 77 en the standard 59 and is.connected at its upper enel to a cross-head 78. Two cross hars 79. andare centrally mounted on a rod 81A for apivot. Two link bars 82 and, 83are loosely mounted at their lower ends in the cross-head "(8 by a pivot8a, and the otherv ends are loosely connected 'with the lowerv endsofthe oross-barsNQ and 80 by pivots 85 and 86, respectively.

Apush-rod rises and descends.

There are two parallel upright posts 101 and 102 mounted at their lowerends in the bed plate 3- to extend upwardly therefrom.

The end thread` guides 111 and 112 (Figs '10and 11) are arranged in pairs and described as follows:

Each pair of these guides is composed el" a lon..Cr ineinher 111 and ashort member 112. l/lenoer 111 extends upwardly from rod l1() and issupported its upper end yupon a pivot'rod 113 mounted in hearingssorured 'to posts 101 and 102, and is provided with a transverse slot114 through which' the rod 81 The short member 112 is pivotall7 mountedupon the rod S1 and extends upwardly; therefrom a shorl` distance. andits upper end is threaded upon the'oscilla'- ingr rod 110.1'he rorl'110also passing" through the 111 being pivoted above and member 112 henigpivoted below oscillating. rod 110, as

represents the r'st operation; Fig. 8 'the second; and Fig. 9 the third.The travel of one pair of the 'thread carriers'is diagrammaticallyrepresented in plan view in Fig. 14, where I indicates a movement of thethread carriers to the front; II a movement to the right; III a movementto the center; IV a movement to the right; V a movement to the front; VIa movement to the left; VII a movement toward the center, and

VIII a movement to the left.' The two inclosed ovals indicate theposition -of the needles, around which the thread make this travel.

In Fig. 15 is a diagrammatic, representa tion of the stitches or loopsof thread so laid by the thread carriers around these needles. In thecenter these threads have a closed loop made by the knitting mechanismas shown. This closed loop is formed at the central position where theconverging thread carrier movement VIII and I approach nearest theconverging thread carrier movements IV and V.

In Fig. 8 the two thread carriers 103 and 104 meet at their lower endsand this is the innermost point in their oscillatory motion. In Fig. 7the lower end of the thread carrier 103 moves to the front and the lowerend of the thread carrier 104 moves to the rear.

'In Fig. 8 the thread carriers 103 and 104 return to their closed orcentral position, and in Fig. 9 the lower end of the thread carriersmove to the position shown in Fig. 7.

It being understood that each set of the side thread guides feed threadsor yarns to the needles of one side only and that these two lsides areconnected or joined together tt the ends by the end thread guides asfolows:

The movement of one pair of end` thread guides is shown at theright-handsidc of Fig. 15, from which figure it will be seen that thethreads which arecontrolled by the end thread guides are manipulated soas to be acted upon by the needles of both sets, thus knitting togetherthe two sides of the fabric at the ends thereof.

The threads passing smoothly over the rounded edge of the spreader bars105 and 106, extend to and throufrh the thread carriers to the needles.

The needle move; .nt will be now d'escribed in general te There are twok of needle movements, one is an alterna pward and downward movement inavertical lane, and the other is an alternate horizcntai3 movement insaid plane. i The front cam shaft 6 in rotating turns with it the cams12 and 13, which impart a reciprocating movement to the shoes 14 and 15.The push-rods 16 and 17 which extend up from said shoes, are connectedat their upper ends (Fig. 13) Withthe needle-lift ing bars 72. Thus theneedles have a regular reciprocating vertical movement by eyes of thereason of the mounting of the hubs of the 'needles on the needle-liftingbar, as represented in Fig. 7, where it is seen that there aretwoconnected needle-lifting bars and their accessories, one for the front,and one for the back of the machine.

The horizontal reciprocation of the needle bars 62 and 63 and of theneedle-lifting bars therewith is caused by the cam 33 on lthe lefthandend of the rear cam shaft 7, as shown in Fig. 1. This cam shaft gives amovement to the rocker bar 35 which is pivotally mounted on the bracket34, and this rocking movement is communicated to the needle ar 62and-through theroclzing lever 66 to yneedle plate 63, back and forth ineach rotation of said cam shaft, it being understood that as the frontneedle bar moves to the right the rear needle plate will move to theleft and vice versa. The length of each horizontal reciprocation isequal to the distance between'two adj acentneedles.

As the threads are knitted into the fabric I tape space 69 and issubjected to the stitchtightening mechanism, as shown in Fig'. 7, andpresently described, and are wound upon the take-up roll or drum (notshown).

The kind of fabric made by this machine cannot be suliciently close andiirm cn a knitting machine (in Vthe first or best quality of goods)without the use of a suitable stitch-tightening device. In my machinethere is provided a stitch-tightening mechanism which draws each row ofstitches as they are formed and are leaving the needles by taking up theslack of the thread. By a combination of cam movements the loops orstitches are closed to any degree required after leaving the needles,and thus the fabric can be made much tighter than has been heretoforepossible in vmachinery of this class.- On each rotation of a front camshaft, the rod' 40 ispulled toward the rear of the machine and thethreads which pass yin front of the two xed .rods and 48 IIE :lessees Aare drawnslightly toward the reer by the i^od.40, operated bythe lever36 and the cam 24, as already described.

ln the knitting process the needle latches nre closed by the descent ofthe needle stein through the thread loopwhich hes justj been laid on theneedle by the thread carriers, and when the loop has been knit into thefabric andthe needleyhas been freed therefrom the rise. of the needlecauses the threads from the thread carriers to engage the needle latchand move it downward into its 'open position, asseen in Figs. I and 9.

lhe oscillating ymovement of the -side thread carri( is` caused by thecams 1S and 19 on the iii-ont cani shaft 6, which earn operating the@ein shoes 20 and 2l canse the puse-rods and alternately to move up anddown. ln moving up this push-rod opens the lezytongs (made up oli' thepivotallv connected bars T7, SO, 82 and 83,) thus opening the spreederbars to their Widest extent, but in moving down the push-rods and closethe lazy tongs.

'The oseillating movement. of the end thread (terriersy is caused by thecams 2T and which cams operating shoes 29 and 30 causes Vthe push-rods3l and to move alternately up and down, thus rocking the hell crank lver 199 and vibrating the rod llo to open and close the end guides asheee-I 1 toiore described.

The neriodicel rise and descent of the needles nre caused by the cams l2and. l

spectively. and this 1i veillent communito bv the comb hars T3 andcoverinrf strips Tel, Thus the needles rise and Vtall periodically inthe ordinary welldnown manner.

lt has been stated that the front com shaft fj rotates twice While therear @ein shalt 7 geared thereto7 rotates once. is also parent that seidshafts rotate in opposite directions. ltn'ill he seen from Fig. @thatcams i?? und are oi such coniiguration peripliernlly thaty push-rods Eland 32 will have two successive upward movements and then two successivedownward movements during each revolution .of shaft 7. t will also beseen from Q that cams i8 and 19 are formed, that push-rods 22 end 23will move up and down once during each rev/olstion of shaft t5, end thatcams l2 and 13 will move rods lo and 17 np and down .once for ezich'revolution ofslieft 6.

The stitch-tihtening device copemt-es with the friction tolte-up rolls53 and 55.

The pulley 48, e shaft 49, rotates saidwith its worm 50 to operate the worm gear 52. This worm gear vbeing faston the shaft on which the rear take-up roll 53 is secured, turns saidroll, which in turn rotates roll 55 through its connected gearings. Theknit fabric is drawn by these rolls and passes to the take-up reel ordrum, not shown.

The stitch tightener operates after each row of stitches has beenformed. The cam 24 on shaft 6 is-so timed with relation to the cams 12and 13 on said shaft and also with the pullev 46 on shaft 6 and thepulley 48 on the s aft 49, that the stitch is tightened when the needlesreach their lowest position.

A variety of other stitches can be made by changing the movements'andrelations of the needles with respect to the oscillating thread carriersand thus the pattern ofthe knit fabric can be changed or varied asdesired.

It will be understood that while I have described and shown my preferredform of construction and operation, I do not limit myself thereto vbutmay vary the same if desired.
